LOAD-SUSTAINING DEVICE.

Application filed May 27, 1918.

To all 'll-ltO'I/t it may concern Be it known that I, VVlLLiAM a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Load- Sustaining Devices, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention aims to provide a load sustaining device that can be advantageously used-1n connection With the chassisof the well known Ford automobile, when substituting a truck or commercial body for the .iac'ture, .efiicient as a yieldable ordinary pleasure or touring body, in order that the same chassis or running gear may be used for trucking or other commercial purposes. When making such a change, it is desirable to increase the strength or carrying qualities of the rear spring or springs of the automobile, to sustain such loads as the spring or springsmay be subjected to.

My invention further aims to provide a load sustainingdevice consisting of com paratively few parts, inexpensive to manudurable, easy to install, and highly means for supporting a vehicle body.

My invention will be hereinafter specifisally described and then claimed,' and reference will now be had to the drawings,

. wherein-- L larged cross satay to illustrate one of the t5 Figure 1 is a rear elevation of a portion of an automobile chassis equipped with a load .sustainer in accordance with this invention;

Fig. 2 is an enlarged verticalsectional view of a-portion of the load. sustaining device; Fig. 3 is a horizontal sectional view taken on the line III-TH of Fig 2; Fig. 4 is an ensectional view of the spring shackle bracket.

As illustrating the application of the load sustaining device, it is deemed only neces devices, and it is to be understood that two of the devices are essential to insure an even balance and support for a body or body frame, relative to the rear axle of the vehicle.

In the drawing, 1' denotes a. rear axle casinghuving a bracket 2 and pivotally con .nected to said bracket'by a bolt or pm 3 is a shackle 4 supporting one end of a spring 5.

The spring 5' is located above the rearaxle channel frame 6 adapted for supporting the rear end of a vehicle body.

Specification of Letters Patent.

H. Mouse,

The elements 1 to G inclusive are of a conventional form, for instance as forn'ling part of a Ford chassis, and'my load sustaining device is connected to the frame 6 and thc bolt or pin 3 of the bracket 9, independent of the rear axle casing 1 and the spring 5. The load sustaining device comprises a channel arm 7 having the ends thereof fiat with the inner end of the arm curved to extend upwardly into the frame 6, between the spring 5 and the top of the frame. This inner end is connected to the frame 6 by a hook or hanger bolt 8 constituting means for firmly securing the arm 7 relative to the frameG. i

The outer fiat end of the arm 7 has an opening 9 and a socket 10, said socket having the walls thereof screwthreadcd toreceive the upper end of a cup or spring seat member 11. At the threaded end of the cup or member 11 there is a peripheral flange 12 which engages the bottom side of the arm 7,

and the bottom of said cup or seat member has an opening 13 providing clearance for a guide rod 14. The lower end of the rod 1 L is in screwthrczuled engagement with a stir rup 15 which has apertured lugs 16 "thereof held on the ends oi? the bolt or pin 3, as best shown in Fig. 4.

- Encireling the rod 14 and the cup or member 11 is a coiled compression spring 17, said spring having the lower convolution thereof bearing upon the stirrup 15 and the upper convolution engaging the flange 12 of the cup or member 11. The ex; pansive force of this spring holds the outer end of the arm 7 a prescribed distance above the stirrup 15, but permits of said arm lowering when the frame 6 is subjected to a load. I

The upper end of the rod 14 has a vretaining washer 18 and a nut or head .19. In the cup or member 11 and encircling the rod 14 between the washer 18 and the bot-- tom of the-cup or member 11 is a coiled compression spring 20 and this spring 00- operates with the spring 17 to the extent of holding the rod 14; relative to the cup or member 11. The spring 20 also serves as a shock absorber by preventing a sudden rebound of the outer end of the arm 7 relative to the stirrup 15, and the device in its on tiretyhas some of the prerequisites of a good shock absorber.

I attach considerableimportance to the, fact that the device mav be easily an casing, and while in the an arm adapted for such changes as fall within the scope quickly installed without changing any part of the present. Ford chassis, although in some instances it 111a) be necessar to substitute a longer shackle bolt or pin 3 for what is ordinarily used. the device does not interfere, handconnections or parts of the rear witlibrake axle illustrated a preferred embodiment of my invention, 1. would harerit understood that the strlu-tural elements are susceptible to appendedclaims.

What 1 claim '1s:-'

1. A load sustaining device comprising attaclnnent to a chassis frame to extend outwardly from the side thereof above a rear axle casing, a stirrup adapted for attachment to a spring shackle bracket, :1 cup connected to the outer end of said arm, a rod tamnected to said stirrup and e. :tendiI=' through said cup, a spring between said stirrup and said arm, and a spring between said cup and the upper end of said rod.

2, load sustaining device comprising an arm adapted to have the inner end thereof connected to a chassis frame, a stirrup adapted for attachment to a shackle bracket,

, arm,

'lhe disposal of drawing there is of the connected to tlie'outer end of said a irod connected to'said stirrup and extending through said cup and the outer end of said arm, aspring around said rod 'and cup between said stirrup and said arm, a head on said rod, and a spring around said rod between said head and" the bottom of said cup.

3. A- load sustaining device comprising a cup ed to said stirrup and extending through and a the outer end of saidfarnn a spring around said rod between said stirrupand the upper end of said cup, a head on the said cup upper end of said rod, and a. spring in said cup between the bottomthereof andthe head on said rod.

In testimony. whereof I atlix my signature in the presence of two witnesses.
